Soybean disease management: chemical and biological control in tropical regions

Successful disease management programs begin with correctly diagnosing the disease; use of cultural techniques consisting mainly of crop rotation, host resistance, and production of high quality seeds; and the use of fungicides to control foliage and seed diseases. Research on host plant resistance has been conducted for anthracnose, bacterial pustule, frogeye leaf spot, leaf rust, and seedborne diseases. Future disease management techniques may include better diagnostic and scouting procedures to predict disease outbreaks; use and evaluation of wild perennial Glycine accessions for resistance to certain diseases; and more reliable recommendations for control through management and cultivar selection. -from Authors
